Original 1st printing 4&5/8 x 6&7/8" blank-reverse concert handbill/card for Jefferson Airplane and the Grateful Dead appearing with Hot Tuna and the New Riders of the Purple Sage at Winterland in San Francisco, CA from 10/4-5/1970.
Art by David Singer show was promoted by Paul Baratta's Winterland Productions.
Medium glossy-coated index stock handbill is in GORGEOUS near mint (A-) condition; just a nearly-invisible vertical press scratch going through the center of the image area and a stray fingerprint or two, otherwise it is an UNBEATABLE 1st printing example of this semi-uncommon Grateful Dead/Airplane handbill from late 1970.
